download youtube video from the smartphone

videos lately used to raise the prestige of a person or group which, from the video, the person can become famous in no time. Especially youtube video site that is famous throughout the world. By using our initially confused smartphone to download videos from youtube because of limited link provided to do the downloading of the video are going to download. The easiest is just streaming from YouTube, which requires not less bandwidth. By using the site to address our http://m.duoberry.com can download the videos either extension mp4, 3gp, and music files of mp3 and ringtone. For more details, please click the link

DBMS

DBMS (Database Management System) is a software that allows the user to define,create, manipulate, and database maintenance. DBMS software that so many kinds,for example: Oracle, MySQL, SQL Server, Ms. Access. Data storage using the DBMSwould be more beneficial such as:
Performance obtained with large enough storage
Data integrity is guaranteed
Independence
Centralization
Securities
For example in the form of visual placement of the DBMS as below:

Principles of Good Wiring

Cable is the foundation of any computer network. Without planning and installation are eligible, problems can arise from things that are not unexpected. In a certain scale, to address the issues of this kind may be needed efforts take time and exhausting, and this often means a network that forced non-active for long periods of hard to predict.For critical networks (critical systems) in an organization that puts the network activity as one of the business requirements, problems that lead to network downtime can not be tolerated. Therefore a comprehensive design, planning, measurable, and installation is a series of structured processes that need to be pursued seriously. The following are the principles that need to be considered in a structured network cabling (Structured cabling Systems-):
• The network has never been smaller or less complexity.
• Build a cabling system that is able to accommodate the needs for voice and data transmission.
• Always install the cable in excess of current needs. Extra cable is not needed now will be useful someday.
• Adhere to the standards set forth in the structured-cabling Standards when building a new cabling system. Avoid using proprietary tech cable.
• Use the cables and components are of high quality. Failure to turn off cable's most sophisticated applications. Quality does not always correlate with the price. Use the cable on the basis of reference, which has proven performance, and reputation of the manufacturer of quality cable.
• Install properly. Even with the best quality cables will not be meaningful without good workmanship.
• Plan for future needs. Just because Ethernet 1000BaseT impressed not too useful at this time, does not mean there will be an absolute need for the next 5 years.
• Documentation, documentation, documentation.

IEEE 802.3

IEEE 802.3 is a frame format which is the result of a merger of the specification IEEE 802.2 and IEEE 802.3, and consists of an IEEE 802.3 header and trailer and a header which the IEEE 802.3 IEEE 802.2 defines the physical layer and media access control sublayer of the data-link layer of the Ethernet standard wired
Here are some examples of standard IEEE 802.3 (Ethernet):
• Speed ​​10Base2 10Mbps, baseband technology, cable lengths up to 185 meters.Known as thinnet and can support up to 3 hosts in a single cable segment. Using a bus topology, both physically and logically with AUI connectors. Number 10 means 10 Mbps, base means using baseband technology, and the number 2 means the maximum distance of 200 meters before requiring a repeater. Network cards (NICs) using 10Base2 BNC connector (British Naval Connector / Bayonet Nut Connector / Bayonet Neill Concelman), and T-connector for connection to the network.
• Speed ​​10Base5 10Mbps, baseband technology, cable lengths up to approximately 500 meters. Known as Thicknet, using the topology of physical and logical bus with AUI connectors. Can reach 2500 meters with several repeaters and able to handle 1024 users for all segments.
• 10BaseT speed of 10Mbps, baseband technology, cable lengths up to 100 meters, using UTP cable category 3 (Cat 3). Unlike the 10Base2 and 10Base5, 10BaseT every device on the network must be connected through a hub or switch, and allowed only one Hub / Switch on each segment of cable. Using the RJ-45 connectors (8-pin modular connector) with a physical star topology and logical bus topology.
• 100BaseTX Speed ​​100Mbps, baseband technology, cable length 100 meters.Using 2 pairs of UTP cable with category 5, 5e or 6. There is only one host in a single cable segment, use an RJ-45 with a star topology (Star) physical and logical bus topology.
• Using 100BaseFX multimode fiber optic cable 62.5/125 micron size with a length of up to 412 meters. Using the ST or SC connectors with the topology of point-to-point.
• 1000BaseT speed of 1Gbps, using Category 5 UTP cable (Cat 5 and Cat 5E) 4 pair, with cable lengths up to 500 meters.
• Represents 1000BaseLX Singlemode fiber optic with a size of 9 microns and the signal emitted by laser 1300 nanometers. Can work with a distance of 30-10 kilometers.
